In an age of digital information and communication, cybersecurity threats cannot be avoided even in the healthcare industry. In fact, healthcare information infrastructures (HCIIs) are targets due to their increasing digital interconnectivity. As such, there is an urgent need for health service operators to protect HCIIs. The EU-funded AI4HEALTHSEC project will develop a solution that improves the detection and analysis of cyberattacks and threats on HCIIs. The aim is to build situational awareness and incident handling and risk assessment among HCIIs. Another important step is providing health operators the capability to react in case of security breaches. AI4HEALTHSEC will also ensure the exchange of reliable and trusted incident-related information, among ICT systems and entities making up the HCIIs.
